BACKGROUND OF INVENTION

1. Field of Invention

Embodiments of the invention generally relate to systems, methods, andapparatus for authenticating identity or verifying the identity ofindividuals and other entities seeking access to certain privileges andfor selectively granting privileges and providing other services inresponse to such identifications/verifications. In addition, embodimentsof the invention relate generally to systems and methods for obtaininginformation from and/or transmitting information to a user device and,in particular, to systems, methods, and apparatus that provide forcontactless information transmission.

2. Discussion of Related Art

Control of access to secure systems presents a problem related to theidentification of a person. An individual may be provided access to thesecure system after their identity is authorized. Generally, accesscontrol to secure computer networks is presently provided by anauthentication scheme implemented, at least partly, in software locatedon a device being employed to access the secure computer network and ona server within the secure computer network. For example, if acorporation chooses to provide access control for their computernetwork, they may purchase authentication software that includesserver-side software installed on a server in their computer system andcorresponding client-side software that is installed on the devices thatare used by employees to access the system. The devices may includedesktop computers, laptop computers, and handheld computers (e.g., PDAsand the like).

In practice, the preceding approach has a number of disadvantagesincluding both the difficulty and cost of maintaining the authenticationsystem and the difficulty and cost of maintaining the security of theauthentication system. More specifically, the software resides in thecorporation's computers where it may be subject totampering/unauthorized use by company employees. That is, theinformation technology team that manages the authentication system hasaccess to the private keys associated with each of the authorized users.As a result, these individuals have an opportunity to compromise thesecurity of the system. Further, any modification and/or upgrade to theauthentication system software is likely to require an update to atleast the server-side software and may also require an update of thesoftware located on each user/client device. In addition, where thecompany's computer systems are geographically distributed, softwareupgrades/updates may be required on a plurality of geographicallydistributed servers.

There is also a need, especially in this post September 11 environment,for secure and valid identification of an individual before allowing theindividual access to highly secure areas. For example, an FBI agent oran air marshal may need to identify themselves to airport security or agate agent, without compromising security. Typically such identificationmay comprise the air marshal or FBI agent showing identification indiciato appropriate personnel. However, there are inherent flaws in thisprocess that allow for security to be compromised, includingfalsification of identification information and failure of the airportsecurity or other personnel to recognize the situation. Of course thisprocess could be automated, for example, by equipping airport personnelor security with access to a database and requiring the FBI agent or airmarshal to appropriately identify themselves to the database, forexample, by again providing identification which airport personnel canthen enter into the database to verify the identity of the personseeking access to a secure area. However, this process also has theinherent flaws in it as described above. In addition, there may be timeswhen airport security or personnel may not be able to communicate withthe database to check the identity of the person seeking access, forexample, when they are not near a computer terminal with access to adatabase or are carrying a hand-held device that does not have anappropriate wireless signal to access the database. In addition, thereis a need to ensure that if such a hand-held device ends up the wronghands, that security is not compromised.

Further, both commercial (e.g., banking networks) and non-commercial(e.g., security systems) information systems often rely on magnetic cardreaders to collect information specific to a user (e.g., a securitycode, a credit card number, etc.) from a user device (e.g., atransaction card). Credit card purchases made in person provide anexample of the most common transaction-type that relies on a userdevice, the credit or debit card, which is read by a magnetic cardreader. User devices that rely on magnetic-stripe based technologymagnetically store information (e.g., binary information) in themagnetic stripe. The magnetic stripe reader provides an interface to alarger computerized network that receives the user's information todetermine, for example, whether to authorize a transaction, to allow theuser access to a secure area, etc.

Recently, such devices have seen technological advances that increasetheir capabilities and improve their security. For example, such devicesmay now include embedded processors, integral biometric sensors thatsense one or more biometric feature (e.g., a fingerprint) of the user,and magnetic stripe emulators. As one result, such devices may providegreater security by dynamically generating the necessary information,for example, generating the credit card number at the time of atransaction. Improved security can also be provided by such devicesbecause more sophisticated authentication schemes can be implementedwith the devices.

In addition, user devices such as transaction cards may now also providefor one or more modes of information transmission other thantransmission via a magnetic stripe/card reader combination. For example,user devices that may transmit information optically or via radiofrequency (“RF”) signal transmission to a compatible system interfaceare now available. Further, the architecture of a user device thatincludes a processor is generally compatible with both the improvedsecurity features described above and the contactless transmission modessuch as optical and RF signal transmission. As a result of the improvedsecurity and greater functionality of some current user devices, thereis a desire to replace magnetic-stripe based user devices with devicesthat include forms of information transmission other than the reading ofa magnetic-stripe.

There is, however, a substantial installed base of interfaces (forexample, at points of sale, at automatic teller machines (“ATM”), andthe like) that include magnetic card readers which are not equipped toreceive information from a user device in any other format other thanfrom a magnetic stripe. As a result of the cost to replace or retrofitthe installed base, efforts to more-widely introduce user devices thatdo not employ magnetic stripe devices have not been developed. Becauseof the potential to substantially reduce fraud, however, the furtherimplementation of such devices is of great interest to financialinstitutions among others. RF devices that transmit informationwirelessly are expected to become much more prevalent and at some point,the predominant form of information transmission for user authenticationbased on a hand-held device, for example, credit card, debit card,drivers license, passport, social security card, personalidentification, etc. Thus, new and improved methods for transitioningfrom a purely magnetic based form of communication to a wireless form ofcommunication are desired.

One current approach that is intended to “transform” a smart card foruse with a magnetic stripe card reader employs a “bridge” device. Thebridge device requires that the smart card be inserted within it. Thebridge device includes a slot for receiving the smart card, a key padwhereby the user may enter information (e.g., a PIN number), and acredit card sized extension member. Operation of the bridge devicerequires that the smart card be inserted within it and that anelectrical contact surface of the smart card engage a similar surfacewithin the bridge device before the bridge device (i.e., the extensionmember) can be used with a magnetic card reader. Thus, the contactlessnature of more advanced information transmission systems is lost withthe bridge device because it does not support wireless signaltransmission.

Accordingly, there is a desire for one or more devices, systems andmethods for accomplishing any of the herein mentioned objectives.

SUMMARY OF INVENTION

There is thus a need for an identification system that will enable aperson to be accurately identified (“identification” sometimes beingused hereinafter to mean either identified or verified) and/orauthenticated without compromising security, to gain access to securesystems and/or areas. Likewise, there is a need for an identificationsystem that will enable a person to be identified universally withoutrequiring the person to carry multiple forms of identification.

Accordingly, this invention relates, in one embodiment, to aninformation system that may be used as a universal identification systemand/or used to selectively provide information about a person toauthorized users. Transactions to and from a secure database may takeplace using a public key/private key security system to enable users ofthe system and the system itself to encrypt transaction informationduring the transactions. Additionally, the private key/public keysecurity system may be used to allow users to validate their identity.For example, in one embodiment, a smart card such as the SecurID™ cardfrom RSA Security, Inc. may be provided with the user's private key andthe USR system's public key to enable the card to encrypt messages beingsent to the USR system and to decrypt messages from the USR system 10.

The system or database of the invention may be used to identify theperson in many situations, and thus may take the place of multipleconventional forms of identification. Additionally, the system mayenable the user's identity to be confirmed or verified without providingany identifying information about the person to the entity requiringidentification. This can be advantageous where the person suspects thatproviding identifying information may subject the identifyinginformation to usurpation.

Access to the system may be by smart card, such as a SecurID™ card, orany other secure access device. The technology enabling the user topresent their identity information may be physically embodied as aseparate identification device such as a smart ID card, or may beincorporated into another electronic device, such as a cell phone,pager, wrist watch, computer, personal digital assistant such as a PalmPilot™, key fob, or other commonly available electronic device. Theidentity of the user possessing the identifying device may be verifiedat the point of use via any combination of a memorized PIN number orcode, biometric identification such as a fingerprint, voice print,signature, iris or facial scan, or DNA analysis, or any other method ofidentifying the person possessing the device. If desired, theidentifying device may also be provided with a picture of the personauthorized to use the device to enhance security.

An example object-oriented database is ObjectStorefrom Object Design of Burlington, Mass. An example of an unstructureddatabase is Notes from the Lotus Corporation, of Cambridge, Mass. Adatabase also may be constructed using a flat file system, for exampleby using files with character-delimited fields, such as in earlyversions of dBASE, now known as Visual dBASE from Inprise Corp. ofScotts Valley, Calif., formerly Borland International Corp.

The main unit 12 may optionally include or be connected to an userinterface 26 containing, for example, one or more input and outputdevices to enable an operator to interface with the USR system 10.Illustrative input devices include a keyboard, keypad, track ball,mouse, pen and tablet, communication device, and data input devices suchas voice and other audio and video capture devices. Illustrative outputdevices include cathode ray tube (CRT) displays, liquid crystal displays(LCD) and other video output devices, printers, communication devicessuch as modems, storage devices such as a disk or tape, and audio orvideo output devices. Optionally, the user interface 26 may be omitted,in which case the operator may communicate with the USR system 10 in anetworked fashion via the communication port 14. It should be understoodthat the invention is not limited to any particular manner ofinterfacing an operator with the USR system.

It also should be understood that the invention is not limited to aparticular computer platform, particular processor, or particularhigh-level programming language. Additionally, the computer system maybe a multiprocessor computer system or may include multiple computersconnected over a computer network. It further should be understood thateach module or step shown in the accompanying figures and the substepsor subparts shown in the remaining figures may correspond to separatemodules of a computer program, or may be separate computer programs.Such modules may be operable on separate computers. The data produced bythese components may be stored in a memory system or transmitted betweencomputer systems.

Such a system may be implemented in software, hardware, or firmware, orany combination thereof. The various elements of the information systemdisclosed herein, either individually or in combination, may beimplemented as a computer program product, such as USR software 18,tangibly embodied in a machine-readable storage device for execution bythe computer processor 16. Various steps of the process may be performedby the computer processor 16 executing the program 18 tangibly embodiedon a computer-readable medium to perform functions by operating on inputand generating output. Computer programming languages suitable forimplementing such a system include procedural programming languages,object-oriented programming languages, and combinations of the two.

As shown in FIG. 2, the computer system 10 may be connected to aplurality of interface centers 27 over a wide area network 28. The widearea network 28 may be formed from a plurality of dedicated connectionsbetween the interface centers 27 and the computer system 10, or may takeplace, in whole or in part, over a public network such as the Internet.Communication between the interface centers 27 and the computer system10 may take place according to any protocol, such as TCP/IP, ftp, OFX,or XML, and may include any desired level of interaction between theinterface centers 27 and the computer system 10. To enhance security,especially where communication takes place over a publicly accessiblenetwork such as the Internet, communications facilitating or relating totransmission of data from/to the USR database 24 or the computer system10 may be encrypted using an encryption algorithm, such as PGP, DES, orother conventional symmetric or asymmetric encryption algorithm.

In one embodiment, the USR system 10 or USR database 24 may be able toauthenticate its identity to a user or other entity accessing the systemby providing an appropriate code which may be displayed on the user'ssmart card, for example a SecurID™ card or its equivalent, or other codegenerator, for example a single use code generator, being employed bythe user. A comparison by the user or the code generator between theprovided number and an expected number can validate, to the user (orother entity) or the code generator, that communication is with thedatabase and not an imposter. In another embodiment, achallenge-response protocol is employed to authenticate the identity ofthe USR system and/or the user to the other.

The database 24 shown in FIG. 1 has a USR database containing entriesrelated to persons 1-n. The data in the USR database may also besegregated, as shown in FIG. 4, according to data type to enableindividual computer modules to handle discrete applications on discretedata types. Segregating the data, as illustrated in FIG. 4, may makeaccess to the database more robust by enabling portions of the data inthe USR database 24 to be accessible even when it is necessary toperform maintenance on a portion of the database. However, storing thedata in the USR database 24 according to the scheme illustrated in FIG.1 may make it easier for a user of the database to make changes tomultiple types of data simultaneously or in a single session. There areadvantages and disadvantages to each data structure, and the inventionis not limited to a particular manner of organizing the data within thedatabase 24, data structures other than the two shown also beingpossible.

As shown in FIG. 3, each entry 30 in the database 24 may containmultiple types of information. For example, in the embodiment shown inFIG. 3, the entry contains validation information 32, access information34, publicly available information 36, address information 38, creditcard and other financial information 40, medical information 42, jobapplication information 44, and tax information 46. The invention is notlimited to a USR containing entries with all of this information or onlythis particular information, as any information on a person or otherentity such as a company, institution, etc. may be stored in USRdatabase 24.

If the database information is split between multiple databases, eachdatabase will typically include at least the validation and accessinformation to enable the USR software to correlate a validation attemptwith a verified validation, and to enable the USR software to determineaccess privileges to the requested data. Alternatively, databases may belinked to permit information not in a main USR database to be retrieved,with validation/identification for all databases accessed being done atthe USR system.

In FIG. 3, the validation information is information about the user ofthe database to whom the data pertains and is to be used by the USRsoftware 18 to validate that the person attempting to access theinformation is the person to whom the data pertains or is otherwiseauthorized to receive it. The validation information may be any type ofinformation that will reliably authenticate the identity of theindividual. For example, in some embodiments, the information mayinclude any of a secret known by the user (e.g., a pin, a phrase, apassword, etc.), a token possessed by the user that is difficult tocounterfeit (e.g., a secure discrete microchip), and/or a measurementsuch as a biometric (e.g., a voiceprint, a fingerprint, DNA, a retinalimage, a photograph, etc.).

The user's identifying information may be manually entered or scanned atthe interface center. However, a variety of types of communication maybe employed to communicate the user's identifying information from theidentification card or token to the computer system. For example, nearfield signal may be employed to communicate information between theidentification card or token and the computer system 10. According toone embodiment, the user's identifying information is included in (orentered via) the user's cell phone where it is then communicated to thecomputer system 10. In one embodiment, the cell phone is also configuredto receive information from the computer system 10 at the interfacecenter 27.

In one embodiment, the user of the database will carry a SecurID™ cardavailable from RSA Security, formerly Security Dynamics Technologies,Inc., of Cambridge, Mass. Use of this card enables secure access to theUSR database without requiring the user to transmit any personalinformation. Specifically, to access the USR database, the cardretrieves a secret user code and/or time varying value from memory andobtains from the user a secret personal identification code. The cardmathematically combines these three numbers using a predeterminedalgorithm to generate a one-time nonpredictable code which istransmitted to the computer system 10. The computer system, specificallyUSR software 18, utilizes the received one-time nonpredictable code todetermine if the user is authorized access to the USR database andgrants access to the USR database if the user is determined to beauthorized. The verification information 32 in the database entry in theembodiment of the invention illustrated in FIG. 3 contains informationto enable the USR software 18 to validate the user using such a card inthis manner.

Alternative types of identification cards or tokens may likewise beused. For example, other smart cards may be used which generatenon-predictable single use codes, which may or may not be time varying,or other access code generators may be used. An algorithm generatingsuch non-predictable codes may also be programmed onto a processor on asmart card or other computing device, such as a cell phone, pager, IDbadge, wrist watch, computer, personal digital assistant, key fob, orother commonly available electronic device. For convenience, the term“electronic ID device” will be used generically to refer to any type ofelectronic device that may be used to obtain access to the USR database.

Likewise, various types of biometric information may be stored in theverification area of the database entry to enable the identity of theuser possessing the identifying device to be verified at the point ofuse. Examples of the type of biometric information that may be used inthis situation includes a personal identification number (PIN),fingerprint, voice print, signature, iris or facial scan, or DNAanalysis. If desired, the verifying section of the database may containa picture to be transmitted back to the person seeking to validate thedevice to ensure the person using the device is the correct person.Optionally, the identifying device itself may also be provided with apicture of the person authorized to use the card to provide a facialconfirmation of the person's right to use the card.

Further, a challenge-response protocol may be employed in combinationwith or as an alternative to the preceding to validate the personattempting to access the information. Various embodiments may employ achallenge-response protocol with or without an identification card.

In FIG. 3, the Access information 34 is provided to enable differentlevels of security to attach to different types of information stored inthe entry 30 in the USR database 14. For example, the person may desirethat their address information be made available only to certain classesof people, for example colleagues, friends, family, Federal Express,U.P.S., and the U.S. mail service. The names or universal identifiersfor those selected individuals, companies, organizations and/or agenciesmay be entered into appropriate fields in the Access information tospecify to the USR software 18 those individuals to whom the addressinformation may be released. Likewise, access fields may be specifiedfor the other types of information. For example, the individual mayspecify that only particular individuals and/or companies have access tothe credit card and other financial information 40, medical information42, job application information 44 and tax information 46. Additionally,the individual may specify that no one have access to that informationunless the individual participates in the transaction (see FIG. 6).

As shown in FIG. 1, the USR software 18 contains algorithms forexecution by the CPU 16 that enables the CPU 16 to perform the methodsand functions of the USR software described below in connection withFIGS. 5-16. The USR software 18, in this embodiment, performs allfunctions associated with validating an electronic ID card. If desired,a separate validation software module may be provided to validateelectronic ID devices outside of a firewall segregating the validationinformation from other user information.

This algorithm comprising the USR software 18 may be used to implement,in one exemplary embodiment, a USR system configured to enable selectedinformation to be disseminated to selected individuals in a secure anddynamic fashion. This information may be used for numerous purposes,several of which are set forth below and discussed in greater detail inconnection with FIGS. 5-16.

For example, the USR system may be used to identify the person, enablethe person to be contacted by telephone or mail anonymously, enable theperson to be contacted by telephone or by mail without revealing theperson's telephone number or present location, enable the person topurchase items over the Internet or in a store without revealing to themerchant any personal identification information or credit cardinformation, enable the person to complete a job application withoutcompleting a job application form, enable the police to discern theperson's identity and any outstanding warrants on the individual, andnumerous other uses. The invention is not limited to these severalenumerated uses, but rather extends to any use of the USR database. Themethods of using the USR database 24 will now be discussed in connectionwith FIGS. 5-16.

FIG. 5 illustrates a method of training the USR database 24. As shown inFIG. 5, the USR software 18 first validates the person's identification(500). The initial validation of the person's identification (500) maytake place at the point of sale of an electronic ID device (for example,a smart card). This may be done in any conventional manner, such as byrequiring the person to show a government issued identification card,passport, birth certificate, etc. Once the person's electronic ID devicehas been issued and initially validated, the validation process proceedsas discussed above.

After the validation process (500), the USR software 18 determines ifthe person has rights to enter data into the system (502). This stepenables the system to charge persons for maintaining information in theUSR database 24. For example, the USR software 18 may poll a database ofcurrent accounts or a database of accounts that are currently in defaultto determine if the person has paid the access fee to enter data intothe database. A similar account status inquiry process may be performedby the USR software 18 in connection with each of the other methods setforth in FIGS. 6-16. If the person is not authorized to enter data intothe USR database 24, the person is notified of the status of theiraccount and the process returns (512) to wait for further input fromanother person. Alternatively, a person may be permitted to enter someclasses of data into the system and update such classes of data at nocharge, with a fee possibly being required for other classes of data,for example medical records. This would facilitate a more robustdatabase.

If the person is authorized, the USR software 18 then enables the personto enter basic personal data into the USR database 24 (504). Optionally,personal data may be one class of data the USR software 18 allows theperson to enter into the USR database 18 regardless of account status,i.e., for free.

The USR software 18 will then check to see if the person has additionalrights to enter additional data (506), such as data to be entered intoone of the other categories of data in FIG. 3. Optionally, this step ofchecking the person's rights to enter data (506) may be combined withthe initial check (502). If the person does not have rights to enter anyfurther data, the USR software 18 notifies the user and returns (512).

If the USR software 18 determines that the person has the right to enteradditional data into the USR database 24, the person is prompted throughthe use of appropriate prompts, provided with forms, and otherwiseenabled to enter advanced personal data into the USR database 24 (508).For each type of data entered, the person is asked to specify the typeof access restrictions and/or whom should be allowed to access theadvanced personal data (510). When the person has completed enteringdata into the database, the process returns (512) and commits the datato the database.

In the situation where only one person has access to enter and/or modifydata for a given person in the database, there should be no conflictwith committing data to the database. If, however, multiple people haveaccess to a given account to modify data, the database may perform anintegrity check to ensure the absence of conflict in the data beforecommitting the new data to the database.

Enabling access to the information in the database will be explained ingreater detail in connection with FIG. 6. As shown in FIG. 6, thedatabase will generally allow anyone to access basic personal data onanyone without performing any authorization check (600).

If information beyond that specified in the basic personal informationarea is requested, the USR software 18 queries whether the requestor hasthe right to access the type of requested data (602). The process ofdetermining the requestor's rights (602) typically involves validatingthe requestor's identity and correlating the identity, the requestedinformation and the access information 34 provided by the person to theUSR database during the training process described above with respect toFIG. 5.

If the USR software 18 determines that the requestor has rights toaccess the type of requested data (604), the USR software 18 instructsthe USR database 24 to enable access to the type of requested data(606). The actual step of enabling access to the type of requested datamay involve multiple steps of formulating a database query, querying theUSR database 24, retrieving the results, assembling the results into auser friendly or user readable format, and transmitting the informationto the user.

If the USR software 18 determines that the requestor does not have theappropriate rights to access the type of requested data (604), the USRsoftware 18 checks to see if the person is participating in thetransaction (608). Checking to see if the person is participating in thetransaction enables the user to authorize access to the requested datain real time. For example, a person may wish to participate in atransaction to give a potential employer one-time access to jobapplication information 44 (see FIG. 3). If the person is notparticipating in the transaction, the USR software 18 determines thatthe requestor is not authorized to have access to the requested data,notifies the requestor of this determination, and ends (610).

If the person is participating in the transaction (608), however, theUSR software 18 validates the person's identity (612) and enables theperson to change access rights to the data (614). If the USR software 18is not able to validate the person's identity, the USR software 18refuses to allow the person to update the database, notifies the personand/or requestor of this determination, and returns (610).

It is also possible that a person may be required to grant access tocertain data, for example financial data such as account numbers, underduress. The system may provide the person with the ability to safelysignal this when accessing the system by using a selected access code orby making a known modification to the access code provided by theelectronic ID device. On receiving such code, the system would takeappropriate steps to protect the person, including for example alertingthe police, tracking the person's location to the extent possible,providing traceable data, and the like.

Once the person has had the opportunity to change access rights to thedata (614), the USR software 18 again checks to see if the requestor hasrights to access the type of requested data (616). Although step 616 mayseem redundant, given the fact that the person is participating in thetransaction and has just previously changed access rights to thedatabase to enable the requestor to have access to the data, step 616 isactually useful at preventing a different type of fraud. Specifically,the requestor may not be forthright with the person regarding the typeof information they are requesting. If step 616 were omitted, the USRsoftware 18 may inadvertently allow access to an unauthorized type ofinformation in the situation where the requestor has surreptitiouslyrequested multiple types of data.

If the USR software 18 determines that the requestor has rights to thetype of data requested (616), it causes the USR database to enableaccess to the type of requested data (606). Otherwise, it notifies therequestor of the decision to deny access to the requested data andreturns (610).

Various applications of the USR database 24 and USR software 18 will nowbe discussed in connection with FIGS. 7-16. These applications aremerely exemplary of the types of applications enabled by the USRsoftware 18 and USR database 24, and the invention is not limited tothese particular applications.

FIG. 7 illustrates one embodiment of a method of using the USR software18 and USR database 24 to purchase goods or services from a merchantwithout revealing to the merchant account information relating to theperson's bank or credit card.

As shown in FIG. 7, when a user initiates a purchase (700), the userenters a secret code in the user's electronic ID device (702) to causethe ID device to generate a onetime code or other appropriate code, andpresents the electronic ID device with the code to the merchant orotherwise presents the code to the merchant. The merchant transmits tothe credit card company (1) the code from the electronic ID device, (2)the store number, (3) the amount of the purchase (704), and the time ofreceipt of the code. The credit card company takes this information andpasses the code from the electronic ID device to the USR software 18(706). The USR software 18 determines if the code is valid, or was validat the time offered, and if valid accesses the user's credit cardinformation and transmits the appropriate credit card number to thecredit card company (708). While the link between the USR system and thecredit card system is a secure link, there is always a danger that thelink may be penetrated and credit card numbers obtained. This may beavoided by instead transmitting, on approval, a multidigit public IDcode for the credit card holder which the credit card company can map tothe correct credit card number. Even if the link is violated, the publicID code is of no value and the secure link prevents this code from beingimproperly sent to the credit card company. The credit card companychecks the credit worthiness of the user and declines the card or debitsthe user's account in accordance with its standard transactionprocessing system (710). The credit card company then notifies themerchant of the result of the transaction (712). In this embodiment, theuser has been able to purchase goods or services from a merchant withoutever providing to the merchant the credit card number. Since theelectronic ID device generates a time variant code or otherwisegenerates a code that can for example only be used for a singletransaction, the merchant retains no information from the transactionthat may be fraudulently used in subsequent transactions.

Another embodiment of a system for facilitating purchase of goods orservices without providing financial information to the merchant is setforth in FIG. 8. In FIG. 8, like FIG. 7, the user initiates a purchase(800), enters a secret code in the electronic ID device (802) andpresents the resultant code to the merchant. The merchant, in thisembodiment, transmits to the USR software 18, (1) the code from theelectronic ID, (2) the store number, and (3) the amount of the purchase(804). The USR software 18 determines if the code is valid (806) and, ifvalid, accesses from the USR database 24 the user's credit cardinformation (808). The USR software then transmits to the credit cardcompany (1) the credit card number, (2) the store number, and (3) theamount of purchase (808). The information in this embodiment transmittedto the credit card company is intended to be in a format recognizable tothe credit card company. Accordingly, the invention is not limited totransferring from the USR system 10 to the credit card company theenumerated information, but rather encompasses any transfer ofinformation that will enable the use of the USR system 10 to appeartransparent to the credit card company.

The credit card company then processes the transaction in a standardfashion, such as by checking the credit worthiness of the person,declining the card or debiting the user's account and transferring moneyto the merchant's account (810). The credit card company then notifiesthe USR system 10 the result of the transaction (812) and the USRsoftware 18 in turn notifies the merchant of the result of thetransaction (814).

In this embodiment, like the embodiment of FIG. 7, the user can use theUSR system 10 to purchase goods or services from a merchant withoutproviding the merchant with the user's credit card number. In theembodiment of FIG. 8, the interposition of the USR system 10 between themerchant and the credit card company is transparent to the credit cardcompany and thus requires no or minimal cooperation from the credit cardcompany to implement.

FIG. 9 illustrates one embodiment of a method of using the USR system 10to verify funds when using a check to purchase goods or services from amerchant. In the embodiment of FIG. 9, the user initiates a purchase andwrites a check to the merchant (900). The check may be a conventionalcheck containing identifying information, or may be a check bearing aunique serial number and no identifying information to enable the checkto be used anonymously.

In either situation, the user enters a secret code into the electronicID card and presents the resulting code to the merchant along with thecheck (902). The merchant transmits to the USR software 18 (1) the codefrom the electronic ID card, (2) the store number, and (3) the amount ofthe purchase (904). Where the check is an anonymous check, the merchantalso transmits to the USR software 18 the check number.

The USR software 18 then determines if the code from the electronic IDis valid (906), and if valid accesses the user's bank information andtransmits to the bank: (1) the user's bank account number, (2) the storenumber, and (3) the amount of the purchase (908). Optionally, the USRsoftware 18 may additionally inform the bank of the check number.

The bank polls its own database to determine if there are sufficientfunds in the user's account (910) and notifies the USR software 18 ofthe result (912). The USR software 18 then, in turn, notifies themerchant of the result of the verification (914).

This check verification system may take place over an unsecuredconnection between the merchant and the USR system 10 since the user'sbank account information is not sent over the connection between themerchant and the USR system 10. Moreover, where an anonymous check isused, the merchant is not even provided with the person's name oraccount information in written form. This provides additional securityagainst unauthorized persons writing subsequent checks.

The check verification system may be conducted over a telephone network,such as by having the merchant call a toll free number or over a networkconnection such as over the Internet.

FIG. 10 illustrates a method of conducting a transaction with a merchantwithout requiring the user to provide to the merchant the user's name,address, or other identifying information, while enabling the merchantto ship the goods to the user. This may be beneficially employed, forexample, in connection with transactions that take place between remoteparties in a networked environment, such as the Internet.

As shown in FIG. 10, the user initiates an anonymous purchase byentering a secret code into the electronic ID device and transmittingthe result to the on-line merchant (1000). The merchant transmits thisinformation to the USR software 18, along with the store number and theamount of the purchase (1002). Optionally, the merchant may provide thestore number and purchase price to the user and the user may send thisinformation directly to the USR software 18 along with the code from theelectronic ID. Where the number from the electronic ID device is a timevarying number, the merchant may also need to input the time the numberwas received. Alternatively, the electronic ID device may encode orencrypt the time with the number, the USR software being able to extracttime when receiving the number from the merchant. This may not berequired where the time varying number varies slowly, for examplechanging every hour rather then every minute as for some existing suchdevices.

In either event, the USR software 18 determines if the code is valid(1004) and, if valid, accesses the user's credit card information fromthe USR database 24 (1006). The USR software 18 then contacts the user'scredit card company, as described above in connection with FIG. 8 (1008)and notifies the USR software 18 of the result (1010).

If the user's credit is declined, the USR software 18 notifies theon-line merchant and the transaction is terminated (1012). If the user'scredit is honored, the USR software 18 polls the USR database 24 for theuser's address and/or address code (1014). Address codes are discussedbelow in greater detail with reference to FIG. 11. The merchant thenpackages the goods into a parcel, labels the parcel with the appropriateaddress and/or address code and ships the parcel to the user (1016).Having the USR system 10 provide the address and/or address code to theon-line merchant enables the user to purchase items in a networkedenvironment without requiring the user to input address information inconnection with every sale.

FIG. 11 illustrates a use of the USR database 24 to deliver mail to auser without requiring the user to provide address information to thesender. This may be useful in many contexts. For example, the user maywish that the address information be known only by the post office. Inthis instance, using the USR database 24 according to the method of theinvention described below, will enable the user to receive parcelswithout requiring the user to provide the merchant with the addressinformation. Additionally, the user's address may change, temporarily,permanently, or frequently. Enabling the sender to send mail by enteringa code instead of an address enables the post office to effectivelydeliver the coded mail to the corresponding address regardless of thefrequency with which the address changes or the duration in which theaddress will remain valid.

In FIG. 11, the user provides an address code on a public area of theUSR database 24 that is available to all persons to see (1100). Thiscode may for example be six alpha characters, which should be adequatefor currently anticipated system populations. Optionally, the user mayprovide this code directly to a merchant or other person desirous ofsending the person one or more parcels.

The user also provides address information to the address informationarea 38 of the user's entry in the USR database 24 (1102). Access to theaddress information 38 is restricted by a rule or other appropriateentry in the access information 34 of the user's entry to only permitmail, parcel or other material delivery services, such as the US mail,UPS and Fed Ex to access the address information.

When someone wishes to have a parcel or other items delivered to theuser, the sender retrieves the user's address code from the USR database24 or otherwise receives the address code from the user, and prints theaddress code on the parcel (1104).

The delivery service accesses the USR software 18, validates itsidentity, and queries the USR database 24 for address informationcorresponding to the address code (1106). The USR database 24 retrievesthe appropriate address data and provides the address information to thedelivery service. The delivery service then either prints out an addresslabel, prints a machine readable bar code to be attached to the package,or correlates an entry in a delivery database between the address codeand the user address (1110). The delivery service then uses thisretrieved information to deliver the package to the user while neversupplying the merchant with the user's permanent or temporary address. Auser may also assure that mail, parcels, etc. are delivered to a currentlocation by providing only a single notice to the USR system, regardlessof how frequently the person moves. The person can also automaticallyprovide for address changes where the person moves according to a knownschedule. Thus, deliveries to be made on a weekday could be directed toone address and deliveries on a weekend to another address; ordeliveries during winter months to one address and during summer monthsto a different address.

FIG. 12 illustrates a method of enabling a person to telephone a user ofthe USR system 10 without providing the user's telephone number to theperson. In the embodiment illustrated in FIG. 12, the user provides atelephone code on the publicly available area of his entry on the USRdatabase 24 (1200). This code may be assigned by the USR software 18 ormade up by the user. The user also provides the USR database 24 withactual telephone information to enable the USR system 10 to connectcallers with the user (1202).

The person wishing to telephone the user of the USR system 10 calls atelephone number and enters the telephone code of the user (1204). TheUSR software 18, optionally, may require the person to identifythemselves to see if they are authorized to call the user. Assuming thatthe person is authorized to call the person, or if no authorizationcheck is performed, the USR connects the person to the telephone numberin the USR database 24 without providing the person with the telephonenumber.

Enabling the user to specify the telephone number may be advantageousfor many reasons. First, the user may frequently be switching betweentelephone coverage areas and may wish to be reachable at all times.Simply by instructing the USR database 24 to connect incoming telephonecalls to one of a myriad of numbers will facilitate connecting theincoming calls to, for example, the user's cell phone, work phone,pager, car phone or home phone, without necessitating the user toprovide all these numbers to the caller. A similar system may beimplemented for facsimile transmissions, e-mails or othercommunications.

The user also may have predefined rules to enable telephone calls tofollow a set pattern. For example, the user may desire to receivetelephone calls only from family members during the night time at home,may wish to have all incoming calls routed to a car phone duringcommuting hours, and may wish to have all incoming calls routed to acell phone during lunch. These time dependent rules may and/or callerspecific rules may be entered into the USR database to specifyaccessibility and connectivity of incoming telephone calls.

The publicly available address code and telephone code and any othercodes may be the same, or may be different, there being some advantagesto having a single code usable for all such applications for each personon the system. The codes could be accessible through a variety of mediaincluding telephone and the Internet. Where two or more people on thesystem have the same name, which will frequently be the case, additionalpublicly available biographical data may be provided with the name toassure that the right code is selected. The system may similarly be usedto provide public keys for use in a public key/private key encryptionsystem, to provide other public codes for an individual or to provideother public information. Access to such information would typically beunrestricted.

Where the system is used to provide public keys, the public code used toobtain the key, or possibly the public key itself, may be used as aboveto obtain the e-mail address, telephone number or the like for theperson to whom the message is being sent, and the USR system may also beused to perform the encryption. When the recipient receives the message,he deencrypts it using the recipient's private key in standard fashion,including deencrypting the name of the sender. However, this does notnecessarily verify the sender and such verification may be desirable forimportant messages, particularly ones involving large financialtransactions. The USR system may accomplish such verification by alsostoring private keys for people in the system. The sender firstauthenticates himself to the system, and the system then adds a secondsignature to the message which is encrypted with the sender's privatekey. The receiving party deencrypts this signature with the sender'spublic key. Since the system only sends such signatures forauthenticated users, the message is thus verified.

FIG. 13 illustrates a general method of using the USR database 24 toauthenticate a user's identification. This may be used in connectionwith any of the other methods disclosed herein to ensure that theelectronic ID device has not been stolen and/or hacked by anunauthorized holder.

Specifically, in the embodiment illustrated in FIG. 13, the userattempts to prove identification to a validator, such as to prove thatthe possessor of the electronic ID device is of sufficient age topurchase alcohol (1300). In connection with this attempt, the userenters a secret code into the electronic ID (1302). The validatortransmits to the USR software 18 the code from the electronic ID (1304).If the USR software 18 determines that the code is valid (1306), itaccesses the user's photograph, age information, or any other desiredinformation, and transmits that information to the validator (1308). Bytransmitting back to the validator a picture of the person to whom theelectronic ID card was issued, the validator can ensure that the personusing the electronic ID card is the proper person. Likewise, thevalidator can ensure, based on the information provided by the USRsystem 10, that the person is as old as the person claims to be.

A specific embodiment of this identification validation procedure isillustrated in FIG. 14. In FIG. 14, a policeman takes the place of thevalidator. In this scenario, however, instead of simply transmitting tothe policeman a validation of the user's identity, such as theirpicture, the policeman may also receive additional information, such asthe user's police records, records of any arrests, outstanding warrants,and other similar information that may be of use to the policeman whendetermining how to handle a particular individual.

FIG. 15 illustrates a process for enabling the user to provide specificinformation to a party, such as medical staff in an emergency room. Asshown in FIG. 15, if the user desires to provide information to a party(1500), the user enters a secret code in the electronic ID device andprovides the electronic ID code to the party (1502). The party transmitsto the USR software 18 the ID code and the party code (1504). The partycode may be a code from for example an electronic device whichidentifies the party, may be a status code which identifies the class ofusers to which the party belongs, for example policeman, emergency roompersonnel, doctor, etc. or may be a combination of both, the status codefor example being encrypted into the ID code. The USR software 18determines if the code is valid (1506), accesses the user's informationin the USR database 24 and transmits available information to the party(1508). In this scenario, the user may be provided with a plurality ofdifferent codes to enter into the electronic ID device depending on thetype of information to be released to the party. For example, the user'sbasic code may be 1234. The fifth digit of the electronic code mayspecify the type of information to be provided, i.e., 1=addressinformation, 2=medical information; 3=telephone information, 4=jobapplication information, etc. Using multiple codes eliminates anyambiguity about the authority provided by the user to the party, butrequires the user to remember additional information.

The above assumes the user is able to provide an ID code when theinformation is required. However, in for example an emergency roomsituation, the user may not be in a position to provide the ID code, butwould still want medical records provided. The release authorization forcertain portions of the user's database could therefore specify that theinformation be released to certain class or classes of individuals andthe USR system would release such information to individuals ororganizations based only on status code. Thus, the status code of anemergency room could alone trigger release of medical data.

FIG. 16 illustrates one embodiment of a method of using the USR database24 to complete a standard application, such as a job application or anapplication to rent an apartment. This embodiment is a specific exampleof the more generic method of enabling a party to retrieve informationdiscussed above with respect to FIG. 15. In FIG. 16, however, the partymay be provided with the opportunity to provide a form to the USRsoftware 18, the fields of which may be automatically completed withinformation from the job application information section of the USRdatabase 24.

As can be seen from the above, many of the users of the USR system areorganizations or agencies such as carriers (post office, UPS, FedEx),communication companies, law enforcement organizations, hospitals andother medical facilities and the like. Each of these organizations canbe provided with specialized software either on a disc or other suitablemedia or electronically, for example over the Internet, which performs anumber of functions, for example automatically generating status codesfor data access requests, controlling information received, andformatting data received in response to a request in a desired way. Thiscan result in an access request from such organization for a given usercausing all data on the user required to complete the form beingretrieved and presented to the organization in the format of their form.A user may also authorize an organization for which a form has beencompleted using the USR system to receive updates, either in response toa request from the organization or at selected intervals, for exampleonce a year, so as to maintain information in the forms current. Sincethe user will be providing information to the system on a regular basis,this is a relatively easy and painless way for the user to maintaincurrent information with many organizations the user deals with.

Another potential use of the system is to permit a person to be locatedwhere only limited biographical information on the person is known.Users of the USR system wishing to participate in this feature could becued to provide non-confidential biographical data when they come on thesystem or at any time thereafter when they decide to participate. Theycan also indicate whether they wish their name given out in response tosuch an inquiry or to merely be alerted to an inquiry which mightinvolve them and information on the requester. A person seeking to findanother person or group of people can input appropriate biographicaldata, for example members of 1975 Harvard University hockey team, orinformation of a person's last known address plus school information,etc. The system will then provide a list of persons who meet the listedcriteria from which the person making the inquiry can hopefully find theperson they are looking for.

In the above application and others, when a person is located, theperson may request that only the person's address code or general accesscode (i.e. a single code which is used to get current address,telephone, e-mail, etc. information) be provided when the person islocated. This can further protect the individual from undesiredcontacts.

Further, although each of FIGS. 13-16 refer to the entry of a secretcode for validation by the USR system, the processes illustrated foreach of FIGS. 13-16 may include a challenge-response protocol by whichthe user's identity is authenticated.

FIG. 17 illustrates another embodiment of the invention. As shown inFIG. 17, the USR system 10 may be used to secure expensive personalequipment, such as stereos, televisions, laptop computers, cellulartelephones, cars, boats, and other items of value to a person. In thisembodiment, each item to be secured using the USR system is providedwith a USR timer chip imbedded in the electronics. If the USR timer chipis not provided with a code within a predefined period of time, forexample every 30 days, the equipment is deactivated. Thus, for example,a television, mobile phone, laptop computer, automobile, heavyequipment, weapon or facility may be provided with a security chiphaving an internal timer that must be reset before expiration byprovision of a particular code. When reset does not occur, the timerwill disable the electronic device or other device using any one of anumber of known disablement methods. Exemplary codes may be transmittedin the same manner as beeper signals are conventionally transmitted ormay be transmitted to wired devices over the Internet or other publicnetwork.

The USR system 10 may be advantageously employed to automaticallyprovide the secured property with the necessary codes at appropriateintervals, unless instructed by the user of the USR system 10 to ceasedoing so. Alternatively, the USR system 10 may require participation bythe user prior to sending out the activation codes.

In this embodiment, the user may provide to the USR system 10,information indicative of the codes to be transmitted, timinginformation, and automation information—i.e., whether the codes shouldbe sent automatically or should require user intervention. Optionally,where the user opts to require user intervention, the USR system 10 maynotify the user of the upcoming deadline via e-mail or another method.

This system may be useful to secure sensitive equipment other thanpersonal equipment as well, such as military equipment, publicequipment, school equipment and any other equipment that is subject totheft.

FIG. 18A illustrates another embodiment of the invention that canprovide a centralized system to control access to a plurality of securenetworks. As shown in FIG. 18A, for example, a system 1800 may employthe USR 10 to control access to a plurality of secure systems 1804(e.g., a plurality of secure computer networks). The system 1800 mayinclude one or more access devices 1802 that can be employed by a userto access a secure computer network included in the plurality of securesystems. In addition, the system 1800 may be employed to protect othersecure systems such as secure communication networks and/or otherresources that are accessed electronically. According to one embodiment,the system 1800 includes a first communication link 1801 that provides acommunication path between the access device 1802 and the USR 10, and asecond communication link 1803 that provides a communication pathbetween the USR 10 and the plurality of secure system 1804. In oneembodiment, each of the first communication link 1801 and the secondcommunication link 1803 are wide area networks, for example, theInternet.

Each of the secure systems 1804 can be associated with an organization.An organization is any entity that employs a secure (e.g., restrictedaccess) host system to provide resources to a plurality of users. Forexample, an organization may be a corporation (including a non-profitcorporation), partnership, other business entity, an affiliation orindividual that employs a secure host system to provide resources to aplurality of authorized users. As should be apparent to those ofordinary skill in the art, an organization is not restricted to anyparticular size, for example, as measured by the number of members oremployees.

More specifically, each of the secure systems No. 1, No. 2, No. 3, etc.may be associated with a different organization and the USR 10 maycontrol access to each of the secure systems. That is, the USR 10 canprovide access control for a plurality of secure computer networks eachassociated with a different and unrelated organization. Further, each ofthe secure computer networks may have a different plurality of users whoare authorized to access the network.

The access device may include any of a desktop computer, a laptopcomputer, and a handheld computer (e.g., a PDA, call phone and thelike). Further, as shown in phantom, a plurality of access devices maycommunicate with the USR 10. Where a web-based system is employed, forexample, each of a plurality of computers connected to the Internet maybe individually employed as a separate access device to communicate(e.g., independently communicate) with the USR 10 to gain access to oneor more of the secure systems 1804.

For example, the access device 1802 may be a computer employed with aclient-server network. In this example, to access resources provided byone of the secure system 1804, the user initiates an access request fora secure system 1804 selected by the user. That is, the user may supplyauthentication information and a computer network ID to the USR. As isdescribed in further detail below, the authentication information andthe computer network ID are processed by the USR to authenticate theuser and determine whether the user is authorized to access the securesystem 1804 that is identified by the computer network ID. The USR thenroutes communications between the user and the secure system providedthat the user authentication is successfully completed.

According to one embodiment, the USR 10 connects the access device 1802to one of the secure systems 1804 via a communication path that does notinclude the USR 10. In an alternate embodiment, the USR 10 connects theaccess device 1802 to one of the secure system 1804 via a communicationpath that does include the USR.

Referring now to FIG. 18B, a system 1810 employs a USR 10 to controlaccess to a secure system (e.g., a secure computer network) according toanother embodiment. In one embodiment, the system 1810 includes the USR10, an access device 1802, and a plurality of secure system 1804.According to this embodiment, the user selects from the plurality ofsecure systems 1804 a secure system that the user would like to access.With the access device 1802, the user communicates authenticationinformation directly to the selected secure system 1804, e.g., withoutgaining access to the system. The secure system then communicates theauthentication information and/or information corresponding to theauthentication information to the USR 10. The USR 10 processes theinformation received from the secure system and then communicates anindication of whether the authentication information corresponds to oneof the plurality of users authorized to access the secure system. Thesecure system grants or denies access to the secure system (and theassociated resources) based on the indication received from the USR 10.

As illustrated in FIGS. 18A and 18B, the USR 10 can provide acentralized access control system (e.g., an authentication system) for aplurality of secure systems 1804 that are associated with independentorganizations that may have no affiliation with one another. Referringto FIGS. 18A and 18B, a first organization may be associated with (haveresources located on and/or accessed by) the secure system no. 1, asecond organization may be associated with the secure system no. 2, andso on. In addition, a single organization may also be associated with aplurality of the secure systems 1804. Thus, in one embodiment, the USR10 provides access control to a plurality of secure systems for a singleorganization.

The systems 1800 and 1810 allow an organization to operate a securesystem without hosting the authentication system software or at leastwithout the need to host a substantial part of authentication systemsoftware. Thus, in one embodiment, software upgrades/maintenance can beimplemented at the USR 10 (e.g., centrally) for the plurality of securesystems 1804 and specialized authentication software is not required atthe access device. In a further embodiment, specialized authenticationsoftware is also not required at the secure system. In versions of theseembodiments, the USR 10 provides a web-based system in which the useremploys a web-browser when communicating with the USR 10 and the securesystem.

The USR 10 can also provide centralized administration and managementfor the plurality of secure systems 1804. The centralized administrationcan include routine tasks such as adding or removing authorized usersfor each of the plurality of secure systems 1804, for example, based onthe hiring or resignation, respectively, of an employee. Additionaladministrative functions such as maintaining a secure database ofprivate keys associated with each user, generating time varying codes,maintaining encryption software, maintaining audit trails and otherfunctions may also be accomplished in a centralized fashion with the USR10 for a plurality of organizations.

In one embodiment, following the connection of the access device 1802 tothe secure system 1804, the USR 10 develops an audit trail by monitoringthe communication path to capture information concerning the use of thesecure system. For example, the USR 10 may collect and store informationconcerning the length of time during which the access device remainsconnected to the secure system, the type of resources accessed by theuser, the type of data transmitted (including the identification ofspecific documents) during a login period and the volume of datatransmitted.

According to one embodiment, the USR continuously monitors thecommunication between a plurality of access devices 1802 and a securecomputer network and collects information to generate an audit trail foreach device. According to another embodiment, the USR does notcontinuously monitor communications. Instead, the secure computernetwork intermittently (e.g., periodically) transmits audit informationto the USR 10 where the audit information may concern one or a pluralityof users connected to the network during a specific time period.

In each of the embodiments, described with reference to FIGS. 18A and18B, the USR 10 may be located in an ultra-secure facility that employsheightened security relative to the security provided by theorganizations that it serves. The physical facility where the USR islocated may meet requirements generally associated with criticalmilitary installations. For example, the USR 10 may be housed in afacility that is hardened against radiation, shielded againstelectromagnetic interference, and/or protected against earthquakes,hurricanes, etc. to allow operation of the USR during times of generalemergency. Further, the personnel and hiring policies of the facilityoperating the USR 10 may also be more secure relative to the securitymeasures taken by the organizations associated with the secure systems1804. That is, the individuals operating the USR 10 may undergo morerigorous background checks that include a detailed investigation oftheir personal and employment histories.

The centralized approach described above can provide increased securitybecause the administration of the access control system (e.g.,authentication software) is in the hands of a highly trusted third partywho has taken heightened security measures regarding the hiring of theadministrative personnel, in particular, the personnel who have accessto authentication data (e.g., private encryption keys, etc.).

In any of the preceding embodiments, the USR 10 may be geographicallyremote from the secure systems.

Further, in any of the preceding embodiments, there may be situationswhere a user employs the access device 1802 to connect to more than oneof the plurality of secure systems 1804. In one embodiment, the user isindependently authorized to access separate secure systems 1804associated with independent organizations. In another embodiment, theuser is authorized to access separate secure systems 1804 eachassociated with the same organization. In either situation, the user mayemploy one or more of the authentication procedures described hereinbefore being allowed access to any one of the secure systems 1804.

Referring now to FIG. 19, a process 1900 that employs a USR to controlaccess to a secure computer network is illustrated. In one embodiment,the process 1900 is employed with the system 1800 illustrated in FIG.18A. At step 1902 an entity initiates an access request. In general, theaccess request will be initiated when the user or entity inputsinformation into an access device such as a computer. At stage 1904, theentity supplies authentication information and a computer network ID tothe USR (e.g., the information is electronically transmitted from theaccess device to the USR). According to one embodiment, the informationis transmitted via the Internet from the access device to the USR. Atstage 1906, the USR receives the access request which includes theauthentication information and the computer network ID. At stage 1908,the USR determines whether the authentication information is valid for auser. According to one embodiment, the USR includes a databasecontaining selected data of a plurality of users authorized to access asecure computer network, and may compare the authentication informationsupplied by the entity with authentication information included in thedatabase to determine whether the authentication information correspondsor is valid for a user. If the authentication information is valid, theprocess 1900 moves to stage 1910 where the USR determines whether theentity is authorized to access the computer network identified by thecomputer network ID. If the entity is authorized to access the computernetwork then the USR may allow communication between the entity and thesecure computer network at stage 1912. As previously indicated, the USRmay route communications between the entity and the secure computernetwork and remain in the communication path employed by the accessdevice to communicate with the secure computer network. Alternatively,the USR may simply provide a connection between the access device andthe secure computer network where the communication path provided by theconnection does not involve the USR.

Returning to stage 1908 if the authentication information supplied bythe entity is not valid for any of the plurality of users then theprocess 1900 moves to stage 1914 where an indication is provided to theentity that access is denied. Similarly, if at stage 1910 the entity isnot authorized to access the computer network identified by the computernetwork ID, an indication is provided that the entity is denied accessat stage 1914. In various embodiments, the entity may be allowedadditional opportunities to successfully access the system.

Referring now to FIG. 20, a process 2000 for controlling access to asecure computer network is illustrated in accordance with oneembodiment. In one embodiment, the process 2000 is employed with thesystem 1810 illustrated in FIG. 18B.

In one embodiment the entity initiates an access request at stage 2002.As described above, the access request can be initiated using an accessdevice and each secure computer network may communicate with a pluralityof access devices. At stage 2004, the entity supplies authenticationinformation to the secure computer network, for example, by entering theinformation in a web browser and transmitting the authenticationinformation over the Internet to the secure computer network. At stage2006, the secure computer network receives the authenticationinformation. At stage 2008, the secure computer network communicatesauthentication information to the USR (or information corresponding tothe authentication information) to allow the USR to authenticate theaccess request. At stage 2010, the USR validates the authenticationinformation to determine whether the entity is authorized to access thesecure system, and at stage 2014, the secure system receives anindication from the USR concerning whether the entity is authorized toaccess the system. In one embodiment, the indication is transmitted fromthe USR to the secure system via the Internet. At stage 2016, the securesystem grants or denies the entity access to the secure system based onthe indication received from the USR.

As should be recognized by those of ordinary skill, the processes 1900and 2000 can be accomplished in a variety of stages that may include anyof the stages described above in various combinations and sequencesincluding one or more of the stages described above in combination withone or more additional stages.

Various embodiments can be employed to control access to a physicalfacility. That is, an electronic device (e.g., a keypad, a card reader,a biometric scanner, etc.) or combination of electronic devices can belocated at an access point to a secure area (e.g., a door, a gate,etc.). The entity initiates the request using the electronic device. Inone embodiment, the physical facility includes all or a portion of thesecure computer network. Thus, in one embodiment, the secure systemreceives an indication of whether an entity is authorized to access aphysical facility. The secure system communicates authenticationinformation to the USR. The USR validates the authentication informationand communicates an indication of whether the entity is authorized toaccess the physical facility. The secure system receives the indicationand grants or denies the entity access to the physical facility.

Each of the embodiments described with reference to any FIGS. 18-20, mayinclude a challenge-response protocol, for example, to authenticate theidentity of the entity and/or the USR system to the other.

FIG. 21 illustrates an embodiment of a system 2100 for validating theidentity of an individual or an entity. The system includes a firstwireless device 2110 and a second wireless device 2112. The firstwireless device 2110 comprises a first wireless transmitter and receiver2114, a first processor 2116 and a first memory 2118. Similarly, thesecond wireless device 2112 comprises a second wireless transmitter andreceiver 2120, a second processor 2122 and a second memory 2124.According to aspects of the invention, the first wireless device and thesecond wireless device are configured to wirelessly communicate witheach other so that the entity associated with the first wireless devicecan communicate his identity to the entity associated with the secondwireless device. It is to be appreciated that the first wirelesstransmitter and the second wireless transmitter can be configured tocommunicate by any form of a wireless signal such as low power Bluetoothsignal, infrared signals, RF signals and electromagnetic signals ingeneral. In accordance with one embodiment, the first wireless deviceand the second wireless device communicate via near field signal.

The first wireless device can also comprise user interface 2126 thatallows the first entity to interact with the first wireless device andcan also comprise a display, such as a LCD display, 2128 that allows thefirst entity to further interact with the first wireless device. Inaccordance with some embodiments the invention, the first wirelessdevice can be configured so that the first entity must enter a PINidentification number, for example, via the user interface to gainaccess to the wireless device. Alternatively, or in addition, the firstwireless device may comprise a biometric sensor or detector 2130 thatenable the first entity to present biometric data to the first wirelessdevice to gain access to the first wireless device. For example, thebiometric sensor can be configured to detect a fingerprint of the firstentity. For such embodiment, the memory 2118 also comprises storedbiometric data of the first entity, which is compared, for example, bythe processor 2116 with the detected biometric data to determine whetherthe first entity is enabled or should be disabled from using the firstwireless device. It is also to be appreciated that the biometric dataneed not be fingerprint data and can be any biometric data known tothose of skill in the art, and that the biometric sensor need not be afingerprint sensor and can be any biometric sensor known to those ofskill in the art.

Similarly, the second wireless device 2112 can also be configured asdiscussed above with respect to the first wireless device, namely withany or all of a user interface 2132, a display 2134 and a biometricsensor 2136 and can be configured to require any and/or all of a secondentity to provide a PIN number, or the second wireless device to matchbiometric information of the second entity with stored biometricinformation to enable or disable the second entity to gain access to thesecond wireless device. Each of the first wireless device 2110 and thesecond wireless device 2112 comprise a power source or a power sourceinterface 2138, 2140 that can be coupled to a power source that providespower to respective devices. It is to be appreciated that the powersource can be any power source, such as, alkaline batteries,rechargeable batteries, proprietary power sources, and interfaces topower sources such as standard 120 VAC, or an AC to DC conversiondevice, as well as any other type of power source known to those ofskilled in the art. In addition, it is to be appreciated that each ofthe first wireless device 2110 and the second wireless device 2112 canalso comprise an additional wireless transmitter and receiver device2142, 2144, respectively, which enable each of these devices tocommunicate wirelessly via other wireless communication systems such as,via any cell phone standard, via satellite communications, over wirelessarea networks, local area networks, wide area networks, as well as anyother wireless communication standard know to those of skill in the art.

According to some embodiments of the system 2100 of FIG. 21, either orboth of the first wireless device 2110 and the second wireless device2112 can be configured to communicate with a secure database 2146, aswill be discussed in further detail herein. According to someembodiments, either of the first or second wireless devices maycommunicate with the secure database on a periodic basis to update it'scorresponding data, or to stay alive as will be discussed herein, or toretrieve information in the secure database that is used in thecommunication protocol between the first and second wireless devices toverify the identity of at least the first entity. Accordingly, it is tobe appreciated that communication with a secure database can be, forexample, via the additional respective wireless transmitters andreceivers 2142, 2144 of the first and second wireless devices, or can bevia a network interface 2152, 2154 of the respective devices, thatcommunicate with a network 2148 and to the secure database 2146.

Referring now to FIG. 22, there is illustrated one embodiment of anoverall communication process that occurs with the system 2100 of FIG.21. In particular, the process is effected by the system of FIG. 1 so asto identify and authenticate the identity of the first user associatedwith the first wireless device 2110 to the second user associated withthe second wireless device 2112. For example, consider the situationwhere an air marshal or an FBI agent is carrying the first wirelessdevice 2110 and airport security or security personnel generally want toensure the identity of the user of the device 2110. The communicationprotocol 200 illustrated in FIG. 22 is one embodiment of a protocol thatenables secure authentication of the first user of the wireless device2110.

According to one embodiment of the process, the first user of the firstwireless device 2110 first authenticates his or herself to the wirelessdevice 2110, for example as has been discussed above, by either enteringa PIN via the user interface 2126 of the first wireless device or byinteracting with the biometric sensor of the first wireless device atstep 202. In various embodiments, a challenge-response protocol isemployed in which the first user supplies information (a biometric, aPIN or other information) to authenticate his or herself to the wirelessdevice 2110. If the user of the device does not enter the correct PINnumber or does not match the biometric data stored in memory 2118 of thefirst authorized user of the device, then the device at a minimum shutsdown at step 204. However, according to some embodiments, the device2110 can also be configured to automatically delete any portion of orall of the data stored in memory 2118 at step 206. In addition, as willbe discussed in further detail herein, according to some aspects of theinvention, the first wireless device can be configured to periodicallycommunicate with the secure database 2146 to remain alive, for example,after the first user of the first device authenticates itself to thefirst device. If the first device does not communicate with the securedatabase at such periodic intervals at step 208, then the first devicecan be configured to delete any or a portion of the data stored inmemory at step 206.

The communication protocol also comprises a second user of the seconddevice to authenticate his or herself to the second device at step 210.It is to be appreciated that the authentication by the second device ofthe second user by any of the mechanisms discussed herein and above withrespect to the first wireless device, including entering a PIN number tothe user interface 2132 of the second wireless device or by interactingwith the biometric sensor 2136 of the second wireless device. Inaddition, it is to be appreciated that as discussed above with respectto the first wireless device, if such identification is not successful,the second wireless device will at a minimum shut itself down at step212. However, it is also to be appreciated that the second wirelessdevice can be configured to automatically delete a portion of or all ofthe data stored in the memory 2124 of the second wireless device, shouldsuch authentication not be successful at step 214. In addition, it is tobe appreciated that the second wireless device can also be configured atstep 216 to communicate with the secure database 2146 within definedperiods of time, or even a periodic interval once the second userauthenticates himself to the second wireless device, and to delete aportion of or all of the data in memory 2124 should such periodiccommunication not occur.

If both the first user and the second user are successful inauthenticating themselves to the first and second wireless devicesrespectively, then a communication protocol is initiated between thefirst wireless device 2110 and the second wireless device 2112 at step218. If the communication protocol is not a valid communication protocolbetween the devices, the devices wait until there is a validcommunication protocol. If the communication protocol is a validprotocol (218 yes), then the first wireless device transmits a firstwireless signal containing encrypted authentication information of thefirst user to the second wireless device 2112 at step 220. The detailsof the communication protocol and the encrypted authenticationinformation will be discussed further herein.

The second wireless device 2112 receives the first wireless signal andprocesses the wireless signal to determine the identity of the firstuser. In particular, as will be discussed herein, according to someaspects of the invention, the authentication of the first user includesdisplaying a picture of the first user to the second user on the display2134 of the second wireless device as a result of the communication fromthe first wireless device to the second wireless device. The user of thesecond wireless device can view the picture on the display and ascertainwhether the first user of the first wireless device is who he or shepurports to be. However, as will also be discussed herein, it is to beappreciated that the second wireless device need not be a device thatrequires a user to interact with it and can be, for example, an unmanneddetection system that receives the first encrypted authenticationinformation and determines from the first authenticated encryptedinformation whether the first user is authorized to gain access to asecured place, a secure network, or a secure computer, to do whateverthe first person is seeking to do. If the first user is not who theypurport to be, the communication process goes back to looking for avalid communication protocol. In addition, the process allows the seconduser or the system associated with the second wireless device to take anappropriate action such as denying access to the secure site at step224.

If the user of the first wireless device is authenticated (at step 222yes), then according to some aspects of the invention, the communicationprocess allows for the second wireless device to transmit a secondwireless signal comprising encrypted authentication information of thesecond user to the first wireless device at step 226. In addition,according to such aspects, the communication protocol and the firstwireless device are configured to authenticate the identity of thesecond user to the first user at step 228. It is to be appreciated thatthe authentication of the second user to the first user can be in any ofthe manners discussed above with respect to the authentication of thefirst user of the first device, such as by viewing a picture of thesecond user as provided on the display 2128 of the first wirelessdevice, by matching one-time information contained in the encryptedauthentication information or via a challenge-response protocol.

In addition, according to some embodiments of the protocol, either orboth of the first wireless device 2110 and the second wireless device2112 may communicate with the secure database 2146 to retrieveadditional information at step 230. Such information, as will bediscussed herein, can include for example, a portion of the biographicdata of the first user of the first wireless device or of the seconduser of the second wireless device, or full biometric information of thefirst user or the second user, which can be communicated back to therespective device and used by the respective device to authenticate theuser. In addition, the information can be periodic updates as providedthe secure database to the respective device, such as will be describedherein, including periodic updates of public keys of a plurality offirst users as stored in memory on the second wireless device, orupdates to public keys of a plurality of second users as stored inmemory on the first wireless device. In addition, such information mayinclude periodic updates of the biometric information of a plurality offirst users as stored on the second wireless device or a plurality ofsecond users as stored on the first wireless device, which can comprisefor example a portion of the biometric information or all of thebiometric information.

Referring now to FIG. 23, there is illustrated one embodiment of variousfields included within the first wireless signal and the second wirelesssignal as transmitted between the first wireless device and the secondwireless device. According to some embodiments, the signal comprises aheader field 302. The header field can be any header field known tothose of skill in the art. In addition, the signal comprises a public IDfield 304, which can comprise, for example, any of name information, abadge number, an employee number, an e-mail address, a social securitynumber, and the like, of the first user. In addition, the first wirelesssignal may also include a digital signature field 306 containing adigital signature of the first user. For example, the digital signaturemay be generated with the user's private PKI key. Further, the firstwireless signal may comprise a one-time time varying code field 308 thatincludes a random code as generated by the first wireless device.According to some embodiments, the digital signature field and theone-time code field can be used, for example by the second wirelessdevice, to allow access to a secure place without the need for a user ofthe second wireless device to interact with the second wireless deviceto authenticate the first user. As an example, referring to FIG. 24, thedigital signature and one time code can be encrypted with the privatekey of the first user and transmitted to the second wireless device. Thesecond wireless device can decrypt the digital signature and one timecode with the public key of the first user at steps 402-404 toauthenticate or not the first user at step 406.

In addition, referring back to FIG. 23, the first wireless signal alsocomprises a PKI encrypted one-time DES key field 310 comprising a PKIencrypted one-time DES key. Further, the first wireless signal comprisesa DES key encrypted biometric data field 312, which includes at least aportion of biometric data of the first user encrypted with the DES key.As will be discussed in further detail herein, according to some aspectsof the invention, the public key of a first user, for example, stored inmemory 24 of the second wireless device can be used to decrypt the DESkey, and the DES key can be used to decrypt at least a portion of thebiometric data of the first user to use in the authentication of theidentity of the first user. According to some embodiments, the firstwireless signal can also comprise another ID data field 314, which cancontain other information such as name, height, weight, eye color oranything else.

It is to be appreciated that although the embodiment of the wirelesssignal discussed in FIG. 23 has been discussed with reference to thefirst wireless signal transmitted from the first wireless device 2110 ofFIG. 21 to the second wireless 2112, that the same protocol can be usedwhen transmitting a second wireless signal from the second wirelessdevice 2112 to the first wireless device 2110 to authenticate theidentity of the user of the second wireless device to the user of thefirst wireless device. It is to be further appreciated that variousfields of the signal can be used and not all of the fields of thewireless signal are needed to authenticate identity of the user.

Referring now to FIG. 24, there is illustrated one embodiment of aprocess 400 as identified by act 222 in FIG. 22 for verifying orauthenticating the identity of the first user of the first device.According to this embodiment, which has been briefly discussed hereinwith respect to FIG. 23, the second wireless device can verify theidentity of the respondent without necessarily interacting with a seconduser by decrypting the first user's digital signature from the digitalsignature field 306 at step 402 and verifying that it is the digitalsignature of the first user, decrypting the one-time code from theone-time code field 308 at step 404, and using this information at step406 to authenticate the first user. If the first user is authenticatedat 406, an appropriate action such as allowing access to the securesite, or computer, or network can be granted.

Referring now to FIG. 25 there is illustrated another embodiment of aprocess 520 for authenticating the identity of the first user at step222 of the communication process of FIG. 22. According to aspects of theinvention, the second wireless device at step 522 receives the firstwireless signal and extracts the PKI encrypted DES key from field 310.The wireless device looks up the public key of the first user frommemory 2124 [See FIG. 21] or from a secure server based on theinformation provided in the public ID field 304 at step 524. The secondwireless device uses the first public key to decrypt the PKI encryptedDES key at step 526. The second wireless device acts on the DES keyencrypted biometric information from the field 312 and uses thedecrypted DES key to decrypt the at least a portion of the biometricinformation of the first user as included in the first wireless signalat step 528.

According to some embodiments, the biometric information included in thefirst wireless signal is a portion of the biometric information of thefirst user and the second wireless device is configured to store aremainder of the biometric information of the first user in memory.According to such embodiments, the process 520 also comprises looking upthe remainder of the biometric information stored in the memory at step530 and combining the remainder of the biometric information with thedecrypted and extracted biometric information to provide completebiometric information of the first user at step 532. According to someaspects of the invention, the biometric information can comprise adigital image of the first user and for such aspects, the digital imagecan be displayed on display 2134 of the second wireless device so thatthe second user can ascertain whether the first user associated with thefirst device is who he or she purports to be. However, it is to also beappreciated that the biometric information can be fingerprintinformation, a voiceprint, DNA codes of the first user, or any otherbiometric information known and used by those of skill in the art.Accordingly, the processor 2122 of device 2112 can also be configured toprocess the combined biometric information to authenticate the firstuser at step 536.

Referring now to FIG. 26, there is illustrated another embodiment of aprocess 620 that can be used to authenticate the identity of the firstuser at step 222 of the process 200 of FIG. 22. According to thisembodiment, some of the steps are similar to the steps of the process520 illustrated in FIG. 25 and accordingly a full description of thesesteps will not be herein duplicated. It is to be appreciated that thisembodiment can be used for example, where the biometric information ofthe plurality of first users is not stored on the second wireless device2112 but is instead stored at the secure database 2146 as illustrated inFIG. 21. In particular, for highly secure applications, where there is aworry that the second wireless device can be compromised (even with thenecessity to authenticate the second user to the second wirelessdevice), the second wireless device can be configured to interact withthe secure database to obtain at least a portion of the biometricinformation of the first user, rather than storing at least a portion ofthe biometric information of the first user in memory on the secondwireless device.

According to such embodiments, the second wireless device can receivethe first wireless signal including the fields discussed above inrespect to FIG. 23, in particular, the public ID field 304 andoptionally the PKI encrypted DES key. According to some embodiments, thePKI encrypted DES key may be used by this process. At step 624, thesecond wireless device accesses public key information of the first userfrom the public keys stored in memory on the second wireless device.However, it is to be appreciated that in some embodiments, the publickeys may not be stored on the second wireless device and for suchembodiments, the second wireless device will communicate with the securedatabase to obtain the public key of the first user also at step 624.According to some embodiments, at step 626 the second wireless devicetransmits a signal to the secure database comprising publicidentification number to identify the second device to the securedatabase, presumably after the second user of the second device hasauthenticated his or herself to the second device. For such embodiments,at step 628, the secure database determines whether the second device isauthorized to access the secure database at step 628. It is to beappreciated that according to some embodiments, this communicationbetween the second wireless device and the secure database can beaccomplished with encrypted signals and in some embodiments theencrypted signals can include using time varying one time codes tofurther secure the communication. If the second device is authorized tointeract with the secure database, the process also comprisestransmitting the first public ID from the second wireless device 2112 tothe secure database at step 630, and with this information, the securedatabase accesses the biometric or identification information of thefirst user at step 632. The biometric or the at least a portion of thebiometric information can then be transmitted by the secure database tothe second wireless device at step 634. Again, this transmission can beencrypted and further include time varying or one time codes to furthersecure the communication. The second wireless device can use thereceived portion of the first biometric information and combine it withportion of the first biometric information provided in the firstwireless signal, or can receive all of the first biometric informationas provided by the secure database and, for example, display it on thedisplay 2134 of the second wireless device 2112 at step 636, or canprocess the biometric or identification information at step 638 todetermine whether the first user is authenticated.

Referring now to FIG. 27 there is illustrated one embodiment of a datastructure 720 that can comprise memory 2124 of the second wirelessdevice 2112. It is to be appreciated that any or all of the variousportions of this data structure can be present in the memory 2124.According to some aspects of the invention, the memory will include theprivate key of the second user at field 722. The private key can beused, for example, when communicating by the second wireless device tothe first wireless device to provide a digital signature of the secondentity encrypted with the second user's private PKI key to the firstuser. In addition, the memory can also comprise a plurality of publickeys of a plurality of first users at area 724. Such public keys of aplurality of first users can be used as has been discussed herein incombination with the private key of the first user to decryptinformation of the first user. For example, the public and private keycan be used to decrypt the DES key of the first user. In addition, thememory can also comprise at least a portion of biometric data of aplurality of first users, at area 726. As been discussed herein, the atleast a portion of the biometric data of the plurality of first userscan be combined with the portion of the biometric data provided in thefirst wireless signal or from the secure database, to create thecomplete biometric data of the first user for ascertaining orauthenticating the identity of the first user as has been describedherein. In addition, the memory can also comprise biometric data of thesecond user at field 728. The biometric information of the second usercan be used, for example, as has been discussed herein to compare thebiometric data detected by the biometric sensor 2136 of the secondwireless device to determine whether the second user is authorized tohave access to the second wireless device. It is to be appreciated thatthe data structure 720 of FIG. 27 can also comprise the memory 2118 ofthe first wireless device 2110, and that any or all of the fields of thedata structure 720 can exist in the memory 2118 in the first wirelessdevice. It is also to be appreciated that the first wireless device canaccess the data structure 720 and the various fields for the samepurposes as discussed above with respect to the second wireless device,namely, to provide the first digital signature of the first entityencrypted with the first private key in the first wireless signal, toaccess the public keys of a plurality of second users for the purpose ofdecrypting information provided in the second wireless signal, to accessat least a portion of biometric information of the second user stored inthe field 726, as well as to compare biometric information of the firstuser with sensed biometric data provided by the biometric sensor 2130 ofthe first wireless device.

For example, embodiments of the invention may employ a protocol thatdoes not require synchronized clocks in each of the user device 104 andthe converter device and/or elsewhere in the system 100 to complete avalidation and/or authentication process. That is, according to oneembodiment, an information exchange between the user device 104 and theconverter device 102 includes a first piece of information transmittedfrom the user device 104 to the converter device 102 and a subsequentchallenge (e.g., an encrypted challenge) generated by the converterdevice and transmitted from the converter device to the user device 104.According to one embodiment, the user employs the user device to respondto the challenge. In one embodiment, the user's response is at least inpart based on information included in the challenge. An identity of auser who responds accurately to the challenge can be successfullyvalidated. In various embodiments, a challenge-response protocolincludes an information exchange whereby the identity of the converter102 is also authenticated by the user with the user device 104.

In various embodiments, the above-described challenge-response protocolmay not require any further action by the user than is required undercurrent approaches that require synchronized clocks in disparatedevices.

In some embodiments, the output device 150 need not transmit anypersonal information associated with the user. For example, commonlyowned U.S. patent application Ser. No. 09/810,703, filed Mar. 16, 2001,entitled “Universal Secure Registry” (“the '703 application”) describesan approach that can improve security and reduce the need for multipleforms of identification. The '703 application is incorporated herein byreference in its entirety. The universal secure registry 118 included inthe system 100 provides one example of the integration of such aregistry into a system that employs a converter device 102. With the USRsystem, for example, the user device 104 can provide some information,e.g., such as a public code of the user, which can be authenticated bythe user, for example by providing an ID through the user interface 124or through biometric sensor 130. The public code can be provided to theUSR via the converter 102, system interface 104, and network 114. TheUSR can then provide back to any of the system interface and theconverter device any or all of device information (e.g., transactioncard information), authorization for a transaction, e.g., where thenetwork or the USR also communicates with the relevant authority, andindicia about the holder of the user device.

The system 100 may include a variety of system interfaces 106 ofdifferent types such as the wireless transceiver 154 and the data port156 in addition to the magnetic card reader 152. Although notillustrated, other system interfaces such as an optical interface, asmart card reader interface or any other system interface known to thoseof skill in the art can also be included. Further, the system interfacesmay be either commonly located or may be geographically distributed suchthat some locations include a wireless transceiver 154, some locationsinclude a data port 156, some locations include a magnetic card reader152, and some locations include a plurality of types of systeminterfaces.

Thus, in some embodiments the output device 150 of the converter device102 may include a data port via which the converter device 102 canprovide data to a network or a networked device. In one embodiment, thedata port is also configured to receive data from the network or anetworked device.

Embodiments of the converter device 102 can be configured to providecommunication to the system interface 106 via any of the precedingapproaches including wireless signal transmission. In a version of thisembodiment, the converter device 102 may receive wireless signals fromthe user device and transmit wireless signals to the system interface106. Further, the converter device may include a transmitter that allowsit to transmit information back to the user device.

Referring now to FIG. 29, a process 260 employing the converter device102 is illustrated in accordance with one embodiment. The process beginsat Stage 262—START. Here, the converter device 102 is in a steady statein which it awaits receipt of a signal from a user device 104. At Stage264, the converter device 102 receives data, for example, a wirelesssignal transmitted from the user device 104. At Stage 266, the converterdevice 266 extracts information from the wireless signal for processing.As one example, the converter device 102 may extract informationcorresponding to the user's identity and/or the identity of theindividual to whom the user device was issued. The extracted informationis then provided to the system interface, for example, it is simulatedas magnetic striped data to the magnetic card reader. At Stage 268, thesystem 100 authenticates the user. In one embodiment, if theauthentication is successful, the process continues at Stage 270. Inthis embodiment, if the authentication is unsuccessful, the processreturns to Stage 262 where, for example, the user may be prompted toattempt to authenticate again.

Various user authentication approaches may be implemented using theconverter device 102. For example, the authentication may be performedlocally, that is, without the need for communication between theconverter device 102 and the system interface 106 and system processor110. In one embodiment, the authentication process employs the universalsecure registry 118. In further embodiments, the authentication processemploys one or more authentication protocols such as public-keycryptography, key exchange protocols, protocols employing one-wayfunctions, and the like that are well known by those of ordinary skillin the art. In other embodiments, however, the authentication mayrequire an exchange of information between the converter device 102 andany of the system interface 106, the network 114, the USR 118 andanother database 112. A challenge-response protocol may also be employedalternatively or in combination with any of the preceding authenticationapproaches.

At Stage 270, the completion of the transaction may be involve any of awide variety of acts including: authorizing a withdrawal of money from auser's account, permitting the user access to a secure area, permittinga user to view medical information concerning themselves or a thirdparty, or permitting the user to access other confidential information.

In addition, in some embodiments, the process 260 includes Stage 274where following authentication the converter device 102 receivesinformation associated with the user. The information may, for example,be necessary for the completion of the transaction. For example, wherethe system 100 is employed in conjunction with a check-authorizationprocess, the converter device 102 may receive an indication that theuser has sufficient funds to cover the amount of the check that ispresented at a point of sale. Alternatively, or in addition, theinformation may include indicia related to the authorized holder of theuser device 104, such as a picture ID. The process 260 is completed atStage 272—END.
